roar_vs_write() writes data in buffer buf to the sound server.

PARAMETERS

vss The VS object data is read from or written to.
buf The buffer to read to or write from.
len The length of the data to be read or written in byte.
error This is a pointer to a integer used to store the error value in
case of error. This can be NULL if not used but it is very
recommended to use this error value to report good error
messages to the user.

can be smaller than the requested size. On error, -1 is returned.
